USB Not Recognized

I connected my Droid Razr to my Win 7 laptop and got a message that the device was not recognized. I rebooted both, nothing. Win 7 keeps telling me that my device is not recognized and I should replace it. Gee, thanks, Microsoft. The USB cord I used was not the cord that came in the Razr box, which is too short for my setup, but I did buy the cord from Verizon. Has anyone else had this problem? Does anyone have a solution?

Everyone, thanks for your answers.

I'm not using a hub, and I tried switching USB ports. That didn't work. What did work was using the cable that came in the box with the phone. The additional cables I bought from Verizon don't work. Without installing anything, but using the cable that came in the box, I plugged the phone into a different Win 7 64 bit laptop, and the computer immediately recognized the device and installed the drivers. Although the cables I bought say "data cables," apparently they're only chargers. Oh, well...

Mine is seen no problem. Try deleting it from device manager and try a different port. Also go in to storage manager and try changing drive letters for laughs. It should see it.

Did you install the drivers for the device because without them installed usually cause the issue you are seeing?

I am running Windows 7 64 bit and have no problem. I would try a different USB cord and a different USB port on your machine. Be sure you are not going through a USB hub.

Never would have thunk it ! Spent 4 hours trying to fix this then used the original USB cable that came with the phone and Voila ! it works !

I guess al USB cables are not made the same ....

Now to fix the MOTOCAST USB problem ....

I never would have thunk it, especially since the Verizon cable is advertised as a "data" cable. And, just to wrap up all the loose ends, I took the cable that came in the box and connected the phone to the original computer that would not recognize the USB device, and guess what??!!?? Just like with my home laptop, the phone was instantly recognized, drivers were installed, and everything worked just fine.

So I have a new question: has anyone had success connecting the phone to a Win 7 64 bit laptop using anything other than the cable that came in the box?

Everyone, thanks for your help!

How can you tell Never had an issue like this with cables that fit and look the same.... Thanks for the help.

The cord may be your problem, but is definitely NOT my problem. I believe it is a Windows 7 problem.

Nothing at all happens now when I plug two different factory Motorola (from the box, original Droid and Droid Razr) cords into my 64 bit Windows 7 Home Professional laptop.

Tethering and USB storage used to work fine and reliably on this laptop with these cords.

Then it became intermittent.

Then it stopped, not unrecognized, just NOTHING, no bonk, no recognition that anything was plugged in.

Here's the kicker. This machine can dual boot Vista on another partition.

When I boot into Vista on this SAME machine and SAME cables, everything works fine, tethering, USB, all.

Then, I rebooted Windows 7 and same thing. Instantly recognized all working fine.

Thoughts?

I am having the same problem as the original poster, crystallet. I have
tried everything; including speaking with Verizon customer support. I even went
to Windows 7 Compatibility Center and downloaded the Motorola Droid Razr Device
Manager on my computer and still no luck. I am using a laptop; brand new
Toshiba (just bought 3 months ago) the original charger that came with
the phone that works got damaged and will not replaceable ever again! My computer doesn’t even
recognize when I plug up my phone and when it does recognize it; it claims that
the driver did not install properly, what!!?? The 9 foot charger sent with the
phone does nothing, and they sent me 2 of them!!! I need help what should I do? **(

Hello Naikaru,

I understand this is a great feature and I would like to help. I believe the issue here is the USB cord. Please DM me your name and mobile number, so I may further assist with an original USB cord. Thank you.
